8 EA L L O C K SPECIFICATION forming part of Letters Patent No. 482,118, dated September 6, 1892.

Application filed May 20, 1892. Serial No- 433,7Z1- (No model.)

To aZZ whom it may concern.- lug and forminga continuation of its opening Be it known that 1, JOHN DOWLING, a citior hole. The inner corners of the slot in the zen of the United States, residing at Altoona, guard are extended or provided with flanges 55 in the county of Blair and State of Pennsyl- F, which terminate close to the spring-tongues 5 Vania, have invented a new and useful Car and are designed to prevent theintroduction Seal-Lock, of which the following is a specifiof an instrument for the purpose of spreading cation. the springs and liberating the bolt, so that This invention relates to improvements in the same may be withdrawn downwardly, as 60 car seal-locks, the objects in view being to prowill hereinafter appear.

I*ld6 a cheap and simple construction of the P designates the bolt or pin, and the same seal class, whereby when applied to a car is provided at its upper end with a head K and connected with thehasp anyopening of the and at its lower end with a head E.

The lower head is somewhat larger than the With these objects in view the invention upper head, and while the said upper head consists in certain features of construction will readily pass through a circular seal S, hereinafter specified, and particularly pointed which is located upon the pin, the lower head 70 out in the claims. will not; but said seal must be cut or-de- Referring to the drawings, Figure 1 is a perstroyed in order to effect such passage. The spective view of a car provided with a lock lower head is also provided with a notchN in constructed in accordance with my invention. its side. An eyeJ is located upon the under Fig. 2 is a detail in perspective of the lock. side of the lower head and a rod R,ternninat- 75 Fig. 3 is a similar view of the bolt. Fig. 4 is ing in eyes, is loosely connected at one end to a bottom view of the lock. Fig. 5 is a detail said eye, the free end of the rod being conin perspective of the seal. Fig. 6 is a transnected to a chain C, whose opposite end is severse section through the guard. curely fastened to the wall of the car.

Like letters of reference indicate like parts The above completes the construction, and So in all the figures of the drawings. the operation is as follows: The door after be- 0 O designates the car, and D the sliding door ing closed has its hasp passed over the central covering the opening therein, which door is or intermediate lug I, after which the upper provided at its front edge with the hasp H. end of the bolt or pin P is passed through the Secured to the wall of the car adjacent to seal S, which seal is slid to the lower end of 85 the door-opening is a metal plate B, and the the bolt or pin against the lowerhead E. The

From the front the upper converging ends of the spring- 0 face of the plate extends a series of outward tongues L, where it is protected by the guard 40 projections or lugs I, I, and 1 each of which or housing Gr. The locking is now complete,

is provided with an opening or hole 1 The and it-will be seen that the springs Lwill prelngs are further provided at their front edges vent a downward withdrawal of the bolt or with aligning-slots 1 By means of pins or pin, and the seal abutting against the lower 5 rivets I are secured L-shaped spring-tongues lug will prevent an upward withdrawal of the L, which extend upwardly through the openbolt or pin. In orderto effect any withdrawal ing in the upper lug to a point above the lug whatever, a knife must be inserted into the I and converge toward their upper ends. Surnotch N and employed to sever the circular rounding these spring-tongues is a somewhat seal, so that the latter can be removed and the 100 cylindrical housing or guard G, which is lonbolt or pin withdrawn upwardly through the gitudinally slotted coincident with the slot openings in the lugs and from between the formed in the front edge of the lug, said guard spring-tongues, which latter, as will be ob being preferably formed integral with said vious, do not resist to any material extent such upward withdrawal. After withdrawal the hasp may be removed and the door opened; but before said withdrawal a disengagement of the hasp with the locking-plate will be impossible.

By means of the chain I am enabled to S9? cure the bolt or pin to the car, so that it is always handy and can be found when wanted, and I provide for the employment of this chain by the series of slots formed in the lug and guard, which permit of the passage therethrough of the rod R, which in reality forms a part of the chain. Were it not for these slots the bolt or pin must be loose, and the same might be misplaced or lost, thus rendering the lock inoperative.

The seal which I em ploy in connection with my improved lock may be made of paper, lead, leather, rubber, or any other equivalent material, and hence I do not limit myself to the use of any one of such materials.

Having described my invention, what I claim is- 1. In a car seal-lock, the combination, with the locking-plate having the series of outwardly-projecting lugs provided with holes, and with slots extendingfrom theirouter edges to theholes,said slots and holes being in alignment, spring-tongues surrounding the upper hole of the series and converging, and a cylindrical guard having a slot mounted on the upper lug and encircling the tongues, of a hasp for engaging the intermediate lug, a locking bolt or pin having upper and lower heads of a diameter less than the holes of the lug, the lower head exceeding in size the upper head,

the seal adapted to pass over the upper head and of a lesser diameter than the lower head, and the chain connected to the bolt or pin and adapted at its opposite end to be connected to a car, substantially as specified.

2. The combination, with the lockplate having the outwardly-projecting lugs provided with holes and inwardly-extending slots, the holes and slots registering, the cylindrical guard surrounding the hole of the upper lug, slotted to agree with the same, and provided at the inner corners of its slot with parallel flanges, and the L-shaped springtongues riveted to the upper lug, extending up into the guard, and having their upper ends converged, of the hasp for engaging the intermediate lug, the bolt 01' pin having the upper and lower heads of less diameter than the holes of the lugs, the lower head exceeding in diameter the upper head and provided with a notch and depending eye, the circular seal adapted to be introduced over the upper head of the pin and rest against the lower head thereof, the rod having opposite eyes, one. which engages with the eye of the bolt or pin, and the chain loosely connected to the lower end of the rod and adapted to be connected to a car, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

JOHN DOWLING. Witnesses:
